Using packages means less code, not more, since you're not rewriting the wheel every time.

Technically not if packages are just the misguided habit of "one package per function" seen in the Node ecosystem. Same amount of code, increased amount of complexity/meta-problems to deal with.

No. Using a package for a single function doesn't preclude code reuse.

Look at underscore.get package. You could write your own recursive key finder (which I have before), and so could every package author, and you'd have 10x the amount of implementations of a recursive key finder.

A single require of underscore.get by you and other authors means you have a single, well tested implementation with a million other users rather than 10 low quality ones.

Why not one package per line of code? One package per expression? Surely, someone will want to reuse var x = a + b.

   const {get} = require("underscore.get");

   get(obj, 'a[0].b', defaultValue);
If your language requires this [1] just to be able to subscript things without going bonkers, it may be time for a new language.

Exactly. If it's a difficult line of code, with edge cases, requiring unit tests, etc. then sure. Algorithms are a great example of this.

Using your own example: how many badly written copies of https://github.com/NarHakobyan/underscore.get/blob/master/un... do you want?
